A balloon filled with a gas will rise or sink depending on the density of the gas inside compared to the surrounding air. If the gas inside is less dense than the surrounding air, the balloon will rise. If the gas inside is more dense, the balloon will sink.
A balloon rises because it is filled with a gas that is lighter than the surrounding air, typically helium or hot air. The lighter gas creates buoyant force, lifting the balloon off the ground.
Heating the gas inside the balloon causes it to expand and become less dense than the surrounding air. This creates a buoyant force greater than the weight of the balloon and its contents, causing the balloon to rise.
The balloon typically contains a gas, such as helium or hot air, that makes it float or rise in the air.ôme balloons are also filled with air or other lighter-than-air gases.
As a balloon rises, the air pressure decreases, causing the gas inside the balloon to expand. This expansion of gas makes the balloon's volume increase, causing it to rise further. Additionally, the decrease in temperature also affects the density of the gas inside the balloon, contributing to its ascent.
Helium. The helium gas in the balloon is lighter than the air outside the balloon.
When the gas (air) in a hot air balloon is heated it becomes less dense. This makes the balloon more buoyant so it rises.Because heating the air inside the balloon makes it less dense than the air surrounding the outside of the balloon, so it will rise.
No Gas Just hot air which is why it is called a hot air balloon. If you were wondering hot air is lighter than cold air which makes it rise so when it is trapped inside the balloon the whole thing will rise.
A balloon filled with a gas will rise or sink depending on the density of the gas inside compared to the surrounding air. If the gas inside is less dense than the surrounding air, the balloon will rise. If the gas inside is more dense, the balloon will sink.
To make a balloon rise in the air, one way is to fill it with a lighter-than-air gas, such as helium or hydrogen. The gas inside the balloon is less dense than the surrounding air, enabling it to float and rise. The amount of gas and the size of the balloon will determine how high it can rise.

if you mean how the hot air in a hot air balloon makes it rise, its because hot air is less dense than cold air. when cold and hot air meet the cold air sinks thus making hot air left to rise.so when you put hot air in a balloon the air would rise. hope this helps.
Heating the gas inside the balloon causes it to expand and become less dense than the surrounding air. This creates a buoyant force greater than the weight of the balloon and its contents, causing the balloon to rise.
Simple...hot air rises..
Hot air balloons typically use propane gas as fuel to heat the air inside the balloon envelope, which makes the balloon rise and float.
Helium is lighter than air, so when it is pumped into a balloon, it displaces the heavier air inside the balloon. This creates a lower density gas mixture inside the balloon, causing it to rise and float in the air.
Heating the gas in the balloon makes it less dense, causing it to become lighter than the surrounding air. This creates a buoyant force that lifts the balloon upwards. As the gas cools, the balloon descends back to the ground.
